Patent CA-2181637-A1 (CA)
Title: Spreading code generator and cdma communication system
Inventor: FUKASAWA ATSUSHI
IPC: H04J13/00
Filed: 1996-07-19
Abstract: A spreading code generator generates a spreading code by modulo-two addition of two internal spreading codes.  The first internal spreading code is part of a pseudorandom noise sequence, created by resetting a pseudorandom noise generator to an assigned initial state at intervals determined by counting a framing signal.  The second spreading code is selected from a set of preferably orthogonal sequences, the selected sequence being repeated at intervals shorter than the period of the framing signal. A code-division multiple-access communication system employs this spreading code generator to generate all spreading codes used at all communicating stations.  One of the spreading codes generated at each station is transmitted as a synchronization signal.

Inventor: SCHWENK JOERG
IPC: H04L9/08
Filed: 1996-07-24
Abstract: Keys k are transmitted in enciphered form in order to establish keys for authorized persons; this is in part regulated by law. In order to comply with the requirements of such regulations and, at the same time, provide an adequate level of security, the present invention describes a procedure that is based on a combination of a key-controlled one-way function and a threshold procedure. This procedure can be used for many purposes; however, it is intended primarily for securing the transmission of a pay-type broadcast program (pay TV, pay radio).

Title: A carvable ptfe implant material
Inventor: SHARBER NORMAN J
IPC: A61L27/34
Filed: 1994-05-04
Abstract: A carvable implant material for use in surgery and especially in plastic and reconstructive surgery. At least two layers of porous PTFE (polytetrafluoroethylene) sheet material are laminated together by an adhesive placed between the adjacent layers of porous PTFE sheet material. Alternatively, a plurality of discrete pieces of porous PTFE may be adhered together by an adhesive. The presence of the adhesive provides a significant increase in stiffness and hence in carvability beyond that possible in a single layer of porous PTFE without the adhesive. Preferred adhesives are thermoplastic fluoropolymers of lower crystalline melt temperature than PTFE, such as FEP or PFA.

Title: Clutch mechanism of coat film transfer tool and coat film transfer tool
Inventor: KOYAMA KOUHEI
IPC: B65H37/00
Filed: 1996-10-04
Abstract: A clutch mechanism having an easy-to-manufacture and inexpensive constitution, by making use of frictional engaging force in thrust direction, in a coat film transfer tool of automatic winding type.  At least at the feed reel side, a clutch mechanism is provided between a driven member of a tape winding portion and a drive side rotary gear for rotating and driving it, and its power transmission makes use of the frictional engaging force in thrust direction between the driven member and drive side rotary gear.  This frictional engaging force can be set by properly adjusting the dimensional relation in thrust direction between the mutual constituent members, and therefore the designing and manufacturing conditions of the constituent members are less strict, manufacture is easy, assembling is easy, and hence the manufacturing cost and device cost can be lowered.

Title: Subglobal area addressing for electronic price displays
Inventor: BRIECHLE GEORGE T
IPC: G06Q30/00
Filed: 1997-06-25
Abstract: An electronic price display system has uniquely addressed electronic shelf labels (ESLs) controlled by a central computer or host.  To save power and communications channel bandwidth, subglobal addressing is defined which permits the central computer to address more than one but less than all of the labels.  In one application of the addressing protocol the central computer causes the subglobally addressed labels to perform some common action such as changing a display to an alternative display.  In another application of the addressing protocol the central computer uses the subglobal addressing to disambiguate when data collisions occur due to more than one label attempting to respond to a global query.

Abstract: A system and method provide a multimedia bookmark for a hypertext  markup  language  file  that  has  Universal  Resource Locator  (URL).   A user wishing to later revisit a presently loaded and displayed HTML file requests the browser to store a bookmark.   The browser scans the HTML file for a keyword.   If the keyword is detected, the browser locates a description of the location of a multimedia bookmark data  (MBD)  file that is disposed  at  a  predetermined  position  in  the  HTML  file  in relation to the keyword.  The browser stores the MBD file with the URL as a multimedia bookmark.  If the browser does not find a keyword,  it scans the HTML document for TITLE information. If detected, the TITLE information is stored with the URL as a traditional, text-only bookmark. The user recalls his list of bookmarks to revisit the HTML file, and is presented with a set of multimedia bookmark representations  (MBRs)  generated from the stored MBDs, as well as text-only bookmarks.   The browser may  change  the  appearance  of,  animate,  or  present  audio accompaniment to an MBR when the user places his cursor over or selects the MBR.   Upon selecting a MBR or text-only bookmark, the browser loads and displays the HTML file at the associated URL.

Title: Address resolution system
Inventor: IWATA ATSUSHI
IPC: H04L12/28
Filed: 1997-08-14
Abstract: In an NHRP (NBMA Next Hop Resolution Protocol) address resolution system for transforming a network layer address to a data link layer address in an NBMA (Non-Broadcast, Multi-Access) network not sharing media, an NHRP processing section provides a function of resolving an address while an ATMARP (Asynchronous Transfer Mode Address Resolution Protocol) processing section provides a function of resolving an address on the basis of the ATMARP. A holding section is selectively accessed by the NHRP processing section or ATMARP processing section for holding address information registered by the NHRP or address information registered by the ATMARP. When the NHRP processing section receives an NHRP resolution request packet requesting for a resolution of the address of a given ATMARP terminal's address, the processing section sends, if the ATMARP terminal and a terminal sent the NHRP resolution request packet do not belong to the same subnetwork, a reply representative of the address information of an interface received the request packet.
